摘要
现代电子侦察系统中,数字信道化接收机扮演着十分重要的角色。研究了工程上常用的两种数字信道化实现方法:多相滤波器组法和短时傅里叶变换STFT法,对他们的实现原理和性能进行了分析比较,并通过仿真进一步验证了两者的性能差异,为侦察接收机设计提供一定参考。
Digital channelized receiver plays an important role in modem ESM system. Two ways for digital channelization are proposed： poly-phase filter banks and STFT. Their differences ofimplement principle and performance are analyzed and verified by simulations. The results will give some references for future ESM receiver designs.
